Jan 1, 2025Summary for 2025-01: Delivered three targeted enhancements and a bug fix across Haiilo Catalyst to boost UX flexibility, configurability, and localization reliability. Introduced a noActive option for cat-tab to permit non-activatable tabs that can still trigger actions (improving modal workflows and accessibility). Added a custom counter slot for input and textarea components, with optional character count logic to support bespoke UX. Fixed date localization by using a fixed reference date with Intl.DateTimeFormat to generate consistent month and weekday names across environments. These changes improve business value by enabling more flexible UI patterns, reducing maintenance costs, and delivering a more predictable user experience across platforms. Technologies demonstrated include TypeScript/JavaScript module design, slot-based component composition, and robust localization techniques.
